Line outgoing method of composite insulator

Abstract

The invention discloses a line outgoing method of a composite insulator, and provides a composite insulator line outgoing bridge. The composite insulator line outgoing bridge comprises a guide line side connecting plate hook, an insulation bridge plate, a tensioning device and a cross arm side connecting plate hook, the cross arm side connecting plate hook is connected with one end of the tensioning device, the other end of the tensioning device is connected with the insulation bridge plate, and the other end of the insulation bridge plate is connected with the guide line side connecting plate hook. According to the line outgoing method, on-site operating personnel complete power failure maintenance work fast, smoothly and efficiently. The on-site operating personnel reflect that the 220kV vertical arrangement composite insulator chain line outgoing bridge is reasonable in design, light, convenient to carry, easy to mount and dismount and low in labor intensity, few personnel are needed, and the on-site application effect is good.

Description

technical field [0001] The present invention relates to a wire outlet method, in particular to a composite insulator wire outlet method. Background technique [0002] At present, the number of 220kV tension poles and towers using vertically arranged synthetic insulator strings is increasing. When performing power outage maintenance operations on such lines, operators must follow the insulator strings out of the wires for maintenance or inspection of clamps, fittings, etc. Since the insulator strings are forbidden to be stepped on, if there is no suitable outlet tool, a relatively cumbersome ladder must be used instead. Due to the use of vertically arranged 220kV tensile composite insulator strings, the distance from the cross arm to the conductor will generally reach about 4m. If a method such as a ladder or pipe is used to directly erect the transition, the ladder or pipe used for the long distance needs to be considered. After bearing the human body load of the workers,...

Problems solved by technology

Due to the use of vertically arranged 220kV tensile composite insulator strings, the distance from the cross arm to the conductor will generally reach about 4m. If a method such as a ladder or pipe is used to directly erect the transition, the ladder or pipe used for the long distance needs to be considered. After bearing the human body load of the workers, the section also needs to be increased. If the use of insulating materials is considered, the weight of the entire outlet tool will reach 20-30kg, which is extremely inconvenient to use on site.

Since the line maintenance points are many and wide and most of the operating points are located on high mountains and high towers, this will greatly increase the labor intensity of the operators, and it is urgent to develop a light and easy-to-carry outgoing method
